Grime is not garage
Grime is not jungle
Grime is not hip-hop and Grime is not ragga.
Grime is a mix between all of these with strong, hard hitting lyrics. It's the inner city music scene of London.
And is also alot to do with representing the place you live or have grown up in.

Grime mc'sspit slower than rave mc's (ie happy hardcore mc's), yet faster than most hip hop mc's. In terms of tempo, grime ranges between 120bpm and 140bpm usually following a 2/4 or 4/4 time signature.
